The use of horizontal starch gel electrophoresis to separate gray squirrel blood serum was investigated. Three sources of variation in the techniques were identified: (1) minor variation within-run; (2) variation across-run; (3) variation due to the sampling technique. The frequencies of the most anodal bands of 42 gray squirrel blood serum protein electropherograms were compared among several woodlots using chi-square contingency tables. On the basis of these frequencies, no differences were found among the woodlot populations of gray squirrels examined in this study. / Master of Science
